ABSTRACT

Various embodiments provide for a registry for augmented reality (AR) objects, which can provide AR objects to a client device to support various software or hardware applications. For instance, some embodiments provide for an AR object registry that facilitates or enables registration of one or more AR objects in association with one or more locations across a planet.

TECHNICAL FIELD

Embodiments described herein relate to augmented reality and, moreparticularly, but not by way of limitation, to systems, methods,devices, and instructions for a registry for augmented reality objects,which can support mixed reality.

BACKGROUND

Presently, geospatial databases can be used to provide three-dimensional(3D) geospatial maps of the world to mobile devices. Typically, a mobiledevice, such as a smartphone, use a Global Position System (GPS) tocanonically associate the mobile device with a coordinate position onEarth, and the coordinate position can be used to query the geospatialdatabase for 3D map data. For instance, given a central point relativeto the coordinate position of the mobile device, a geospatial data basecan be queried to obtain all data for 3D map objects within a particularradius of the central point, or to obtain the data for the 3D mapobjects closest to the central point.

DETAILED DESCRIPTION

Various embodiments provide systems, methods, devices, and instructionsfor a registry for augmented reality objects, which can provideaugmented reality objects to a client device to support various softwareor hardware applications (e.g., mixed reality software applications).For instance, some embodiments provide for an augmented reality (AR)object registry that facilitates or enables registration of one or moreAR objects in association with one or more locations across a planet(e.g., on a world scale). For instance, an AR object registry can enableassociations between one or more AR objects and one or more locations orphysical objects on planet Earth. In doing so, such an AR objectregistry can permit a user to use their client device to explore ARobjects anywhere on Earth. Additionally, an AR object registry describedherein can also support or enable, for example, implementation of aspatial-based (e.g., augmented reality-based) world wide web.

The architecture of some embodiments described herein permits scaling toservice AR object registration in connection with locations acrossEarth, and permits scaling to provide or support interactive sessionsthat enable multiple users (e.g., large numbers of users) across theworld to interact together with registered AR objects. For someembodiments, an AR registry of an embodiment can associate (e.g., unite)topology map data (e.g., of Earth) with AR object data such that thereal-world information is brought into a virtual model, which enablesthe scalability of the AR registry. Additionally, some embodimentsimplement one or more rankers or ranker mechanisms (e.g., rankeralgorithm) to determine (e.g., by filtering or sorting) which AR objectsare provided to a client device (e.g., in response to a request/queryfor AR objects from the client device). In this way, such embodimentscan affect which AR objects are displayed or surfaced by the clientdevice at and around the client device's current set of coordinates on amap (e.g., geospatial map).

Unlike conventional technologies (e.g., traditional geospatialdatabases), the AR registry of various embodiments can better supportuser interaction with registered AR objects. Additionally, unlikeconventional technologies, the AR registry of various embodiments doesnot need to rely on strict (e.g., tight) geofencing to provide ARobjects to client devices.

As used herein, an AR object can comprise a virtual object that can bepresented in a client device-generated view of a real-world environment(e.g., a view presented on a display of a mobile client device), wherethe virtual object can interact with or enhance a real-world physicalobject of the real-world environment presented in the view. Forinstance, an AR object can be combined with a live (e.g., real-time ornear real-time) camera feed such that when the AR object is presented,it appears situated in the live a three-dimensional environment (e.g.,AR object appears to occupy a consistent three-dimensional volume anddynamically changing in aspect responsive to movement of the camera in amanner similar to that which would have been the case were the AR objecta real-world physical object). A registered AR object can comprise an ARobject registered by an embodiment described herein, thereby associatingthe AR object with a set of coordinates via an AR object registry. Thelevel of interaction (e.g., user interaction) available for an AR objectregistered by an embodiment can vary. For example, an AR object can bestatic and have no level of interaction with a user or the real-worldenvironment. A registered AR object (e.g., virtual ball) can have one ormore available interactions (e.g., spin, bounce, toss, etc.) where anychanges to the state of the AR object (by way of those availableinteractions) are localized (e.g., confined or limited) to the user atthe client device (e.g., state changes to the AR object are notpropagated to another user at another client device) and any changes tothe state of the AR object do not alter the current initial state of theAR object as stored in the AR object registry. A registered AR object(e.g., virtual graffiti) can have one or more available interactions(e.g., drawing, generating, or applying the virtual graffiti) where anychanges to the state of the AR object (by way of those availableinteractions) are propagated to another user at another client device(e.g., be presented in a view displayed by the other client device)without interaction by the other user (i.e., no interactive sessionneeded). Additionally, a registered AR object can permit two or moreusers to interact (e.g., in real-time) with the registered AR object(e.g., spin, bounce, or toss the virtual ball) at the same time duringan interactive session. For example, a first user can toss a virtualball between one or more other users within the same interactivesession, where data is transmitted between the user's client devicethrough the interactive session. Depending on the registered AR object,at the end of the interactive session, the final state of the registeredAR object (as changed by users' interactions during the interactivesession) may or may not be saved to the AR object registry, therebyupdating the initial state of the AR object for subsequent single-userinteractions or multi-user interactive sessions.

For some embodiments, a registration of an AR object or a ranker can beephemeral (e.g., accessible for only a duration of time after firstbeing accessed). The ephemeral nature of a registration can create aneed for a user to re-register an AR object or a ranker periodically(e.g., every 24 hours), which can deter or prevent registration abuses(e.g., spamming).

For some embodiments, user interactions with respect to a given ARobject can be defined by a set of rules (e.g., interaction rules)associated with the AR object. For instance, a rule for an AR object candetermine an availability of an interaction with respect to the ARobject (e.g., can toss or bounce virtual ball), or can define aninteraction constraint with respect to the AR object (e.g., interactionswith respect to the virtual ball are limited to the client, or thevirtual ball can only be tossed so far).

The description that follows includes systems, methods, techniques,instruction sequences, and computing machine program products thatembody illustrative embodiments of the disclosure. In the followingdescription, for the purposes of explanation, numerous specific detailsare set forth in order to provide an understanding of variousembodiments of the inventive subject matter. It will be evident,however, to those skilled in the art, that embodiments of the inventivesubject matter may be practiced without these specific details. Ingeneral, well-known instruction instances, protocols, structures, andtechniques are not necessarily shown in detail.

Reference will now be made in detail to embodiments of the presentdisclosure, examples of which are illustrated in the appended drawings.The present disclosure may, however, be embodied in many different formsand should not be construed as being limited to the embodiments setforth herein.

FIG. 1 is a block diagram showing an example system 100, for exchangingdata (e.g., relating to AR objects) over a network 106, that can includean augmented reality (AR) object system, according to some embodiments.The system 100 includes multiple client devices 102, each of which hostsa number of applications including a client application 104. Each clientapplication 104 is communicatively coupled to other instances of theclient application 104 and a server system 108 via a network 106 (e.g.,the Internet).

Accordingly, each client application 104 can communicate and exchangedata with another client application 104 and with the server system 108via the network 106. The data exchanged between client applications 104,and between a client application 104 and the server system 108, includesfunctions (e.g., commands to invoke functions) as well as payload data(e.g., AR object, text, audio, video or other multimedia data).

For some embodiments, a particular client application 104 provides itsrespective client device 102 with one or more augmented reality/mixedreality features. A particular client application 104 can represent, forexample, an augmented reality (AR) client software application, or amessaging software application that includes augmented reality/mixedreality features. A particular client application 104 can obtain one ormore AR objects (e.g., from an augmented reality (AR) object system withAR object system 116, hereafter the AR object system 116) to generate amixed reality environment (e.g., based on the real-world environment ofthe client device 102) that includes the one or more AR objects. Forinstance, a particular client application 104 can enable a client device102, such as a smartphone, to capture image frames of a real-worldenvironment (e.g., using smartphone camera) and generate a view (e.g.,on the smartphone display) that presents the real-world environment with(e.g., enhanced by) one or more AR objects that are associated with thatreal-world environment. In particular, a particular client application104 can obtain AR objects from an AR registry (e.g., implemented by theAR object system 116) by, for example, requesting or querying for one ormore AR objects from the AR object system 116 using informationassociated with the client device 102, such as information regarding theuser of the client device 102, the current set of coordinates (e.g., GPScoordinates) of the client device 102, or a specified radius around theclient device 102. When obtaining the one or more AR objects (e.g., theAR object system 116), a particular client application 104 can receivedata for those AR objects. The data for those AR objects can include,for example: model data for one or more three-dimensional models (e.g.,3D graphical content) for rendering and displaying the obtained ARobjects on a client device 102; rule data describing one or more rulesthat determine user interactions with the obtained AR objects through aparticular client application 104; or state data describing initialstates of the obtained AR objects (e.g., initial state in which anobtained AR object will be presented by a particular client application104 on a client device 102).

With respect to usage of an obtained AR object, a particular clientapplication 104 can display the obtained AR object on the display of aclient device 102 by determining a positioning of the AR object on thedisplay relative to the real-world environment. A particular clientapplication 104 can do so by executing a process that generates (orconstructs) a virtual camera by combining data from a client devices102's various sensors, such as an image sensor, inertial measurementunit (IMU), and GPS sensor, and then using the virtual camera toposition the obtained AR object on the display of the client device 102.A particular client application 104 can, for example, use a simultaneouslocalization and mapping (SLAM) or visual odometry (VIO) system ormethod to generate the virtual camera. When a particular clientapplication 104 displays the AR object, the 3D model of AR object can berendered and displayed as an overlay over the real-world environmentbeing presented by a client device 102.

For some embodiments, a particular client application 104 enables a userto register one or more AR objects with an AR registry (e.g.,implemented by the AR object system 116) in association with a set ofcoordinates on a map (e.g., geospatial map).

The server system 108 provides server-side functionality via the network106 to a particular client application 104. While certain functions ofthe system 100 are described herein as being performed by either aclient application 104 or by the server system 108, it will beappreciated that the location of certain functionality either within theclient application 104, the server system 108 is a design choice. Forexample, it may be technically preferable to initially deploy certaintechnology and functionality within the server system 108, but to latermigrate this technology and functionality to the client application 104where a client device 102 has a sufficient processing capacity.

The server system 108 supports various services and operations that areprovided to the client application 104. Such operations includetransmitting data to, receiving data from, and processing data generatedby the client application 104. This data may include message content. ARobject-related information (e.g., model data, orientation, interactionrules or logic, state information, interactive, session information,etc.), client device information, geolocation information, mediaannotation and overlays, message content persistence conditions, socialnetwork information, and live event information as examples. Dataexchanges within the system 100 can be invoked and controlled throughfunctions available via user interfaces (UIs) of the client application104.

Turning now specifically to the server system 108, an ApplicationProgram Interface (API) server 110 is coupled to, and provides aprogrammatic interface to, an application server 112. The applicationserver 112 is communicatively coupled to a database server 118, whichfacilitates access to a database 120 in which is stored data associatedwith operations performed by the application server 112.

Dealing specifically with the Application Program Interface (API) server110, this server receives and transmits message data (e.g., commands andmessage payloads) between the client device 102 and the applicationserver 112. Specifically, the API server 110 provides a set ofinterfaces (e.g., routines and protocols) that can be called or queriedby the client application 104 in order to invoke functionality of theapplication server 112. The API server 110 exposes various functionssupported by the application server 112, including for example: accountregistration; login functionality; the sending of AR object-relatedinformation (e.g., model data, orientation, interaction rules or logic,state information, interactive, session information, etc.) via theapplication server 112, from the AR object system 116 to a particularclient application 104; the sending of AR object-related information(e.g., query or request information, user input information, stateinformation, model data for a new AR object, etc.) via the applicationserver 112, from a particular client application 104 to the AR objectsystem 116; the sending of messages, via the application server 112,from a particular client application 104 to another client application104; the sending of media files (e.g., digital images or video) from aclient application 104 to the messaging server application 114, and forpossible access by another client application 104; the setting of acollection of media content items (e.g., story), the retrieval of a listof friends of a user of a client device 102; the retrieval of suchcollections; the retrieval of messages and content, the adding anddeletion of friends to a social graph; the location of friends within asocial graph; and opening an application event (e.g., relating to theclient application 104).

The application server 112 hosts a number of applications, systems, andsubsystems, including a messaging server application 114, an AR objectsystem 116, and a social network system 122. The messaging serverapplication 114 implements a number of message processing technologiesand functions, particularly related to the aggregation and otherprocessing of media content items (e.g., textual and multimedia contentitems) included in messages received from multiple instances of theclient application 104. As will be described herein, media content itemsfrom multiple sources may be aggregated into collections of mediacontent items (e.g., stories or galleries), which may be automaticallyannotated by various embodiments described herein. For example, thecollections of media content items can be annotated by associating thecollections with captions, geographic locations, categories, events,highlight media content items, and the like. The collections of mediacontent items can be made available for access, by the messaging serverapplication 114, to the client application 104. Other processor- andmemory-intensive processing of data may also be performed server-side bythe messaging server application 114, in view of the hardwarerequirements for such processing.

For a given a collection of media content, one or more annotations ofthe given collection may represent features of the given collection, andthose features may include one or more graphical elements (e.g., emojisor emoticons) that various embodiments described herein may be use whenautomatically associating one or more graphical elements with the givencollection. Access to the given collection of media content items mayinclude access to one or more of annotations of the given collection andone or more graphical elements associated with the given collection byvarious embodiments described herein.

As shown, the application server 112 also includes the AR object system116, which implements one or more aspects of various embodimentsdescribed herein, such as an AR registry and ranker-based AR querying.More regarding the AR object system 116 is described herein with respectto FIG. 2.

The social network system 122 supports various social networkingfunctions and services, and makes these functions and services availableto the messaging server application 114 and the AR object system 116. Tothis end, the social network system 122 maintains and accesses an entitygraph within the database 120. Examples of functions and servicessupported by the social network system 122 include the identification ofother users of the system 100 with which a particular user hasrelationships or is “following”, and also the identification of otherentities and interests of a particular user.

The application server 112 is communicatively coupled to a databaseserver 118, which facilitates access to a database 120 in which isstored data associated with operations performed by the messaging serverapplication 114 or the AR object system 116.

FIG. 2 is block diagram illustrating an example logical architecture forthe AR object system 116, according to some embodiments. Specifically,the AR object system 116 is shown to comprise data layers 210 andaugmented reality (AR) object services 230, which support variousfeatures and functionalities of the AR object system 116. As shown, thedata layers 210 comprises a three-dimensional (3D) topological datalayer 212, a logical topological data layer 214, a user data layer 216,and an augmented reality (AR) object model data layer 218. As alsoshown, the AR object services 230 comprises an augmented reality (AR)object interactive session service 232, an augmented reality (AR) objectquery service 234, and an augmented reality (AR) object registry service236. For various embodiments, the components and arrangement ofcomponents of the AR object system 116 may vary from what is illustratedin FIG. 2. Any components of the AR object system 116 can be implementedusing one or more processors (e.g., by configuring such one or morecomputer processors to perform functions described for that component)and hence can include one or more of the processors. Furthermore,according to various embodiments, any of the components illustrated inFIG. 2 can be implemented together or separately within a singlemachine, database, or device or may be distributed across multiplemachines, databases, or devices. For example, the data layers 210 can beimplemented by one or more databases (e.g., databases 120), and the ARobject services 230 can be implemented by one or more servers (e.g., theapplication server 112).

The 3D topological data layer 212 comprises data that describes aninternal representation of a real-world environment. The data caninclude, without limitation, 3D modeling information of the real-worldenvironment and information that associates the 3D modeling informationwith one or more coordinates (e.g., on a topological map). A query tothe 3D topological data layer 212 cam comprise one or more coordinateson a map (e.g., topological map) and a radius value around a pointcorresponding to the one or more coordinates. The query results providedby the 3D topological data layer 212 can comprise one or more 3D modelobjects that fall within the radius that is centered at the one or morecoordinates. Data for the 3D topological data layer 212 can be sourcedfrom one or more data sources, including third party vendors.Additionally, data of the 3D topological data layer 212 can be dividedinto two or more types, such as lower resolution data (hereafter,referred to as world data) and higher resolution data (hereafter,referred to as deep world data. World data can represent default groundtruth data for the AR object system 116 (which can provide a quickfoundation for AR object model placement). In comparison to deep worlddata, world data can have lower accuracy (e.g., approximately 3 m ofaccuracy), and generally lacks indoor data for real world structures(e.g., buildings, etc.). Deep world data can represent the 3Dtopological data having the highest accuracy within the AR object system116 (e.g., centimeter level of accuracy), and can include indoor datafor real world structures.

The logical topological data layer 214 comprises data that relates tologic (e.g., business or operational logic) that can be applied to dataprovided by the 3D topological data layer 212. At least portion of thedata provided by the logical topological data layer 214 can be stored ingeospatial vector type format. Two types of data provided by the logicaltopological data layer 214 can include zone data and geolocation data.

According to some embodiments, zone data (of the logical topologicaldata layer 214) marks or identifies one or more areas in a real-worldenvironment, and can further associate one or more attribute values tothose one or more areas. For instance, zone data can mark/identify areasof a real-world environment according to one or more of the following:state lines, county lines, city limits, parcel traits, or zoning areas.These marked/identified areas may also be referred to or regarded aszones. Within zone data, an area of a real-world environment can bedefined by a non-scalar polygon data type. For some embodiments, zonedata facilitates geo-partitioning of a large real-world environment(e.g., the Earth), which can support assignment and management ofinteractive sessions and session-related computing resources (e.g.,session servers) by the AR object interactive session service 232 asdescribed herein.

For some embodiments, zone data marks or identifies one or morepermissions for a given area (e.g., as one or more attribute values ofthe given area). The permissions (embodied as permission data) for agiven area can enable the AR object system 116 (e.g., the AR objectregistry service 236 thereof) to determine, for example, whether a givenuser can register (e.g., place) an AR object (e.g., new AR object or anexisting AR object) of their choosing at location corresponding to a setof coordinates on a map (e.g. topological map). In this way, zone dataof some embodiments can associate a particular real-world space with oneor more permissions that can deter an abuse of the AR object system 116.For instance, permission data (provided by zone data) can prevent afirst user representing a first business (e.g., pizza shop #1) fromregistering an AR object (e.g., AR object representing a coupon for thefirst business) at a location corresponding with a second business thatis a competitor of the first business (e.g., pizza shop #2). On theother hand, the same permission data can permit a second user that isconfirmed to be the owner of the second business to registering an ARobject of their choosing at the location corresponding with the secondbusiness. In similar manner, one or more permissions provided by zonedata can control registration of AR objects with respect to locationscorresponding to private residencies.

Additionally, one or more permissions provided by zone data for a givenarea can enable the AR object system 116 (e.g., the AR object registryservice 236 thereof) to determine whether a given user can register(e.g., associate) a ranker with respect to a location corresponding to aset of coordinates on a map (e.g. topological map). As described herein,a ranker can determine which AR objects are provided (e.g., surfaced) toa client device in response to a request or query from the client devicefor AR objects.

The following Table 1 can represent an example structure of a databasetable used to store zone data of the logical topological data layer 214.

TABLE 1 Column Name Data Type Brief Description zone_id Long number,Unique ID identifying a marked (serving as a area of real-worldenvironment. primary key) user_id Long number ID for user (correspondingto a (serving as a user_id in table of User Data foreign key) Layer)associated as an owner of this marked area. zone_geometry GeoJSONpolygon Describes the marked area as a real-world region (e.g., aproperty parcel). permission_id Enumeration Describes one or morepermissions associated with the marked area.

According to some embodiments, geolocation data (of the logicaltopological data layer 214) comprises data for storing registration ofan AR object in association with one or more coordinates correspondingto a location on a map (e.g., topological map), storing registration ofa ranker in association one or more coordinates corresponding to alocation on a map, or some combination of both. In particular, for someembodiments, the geolocation data can associate data from 3D topologicaldata layer 212 (e.g., such as geospatial data) with model data from theAR object model data layer 218. In this way, the geolocation data canfacilitate registration (e.g., placement) of an AR object in associationwith a set of coordinates corresponding to a location on a map. For someembodiments, the geolocation data associates a center (e.g., centeroid)of an AR object with the set of coordinates. The center of an AR objectcan correspond to a center of the AR object's 3D bounding box. When theAR object is ultimately displayed by a client device, the AR object'sdisplayed position and orientation can be determined relative to thecenter of the AR object. Additionally, for various embodiments, thegeolocation data facilitates registration of a ranker in associationwith a set of coordinates corresponding to a location on a map byassociate data from 3D topological data layer 212 (e.g., such asgeospatial data) with an identifier associated with a ranker.

Depending on the embodiment, the geolocation data can be implemented asa join table of a database. The following Table 2 can represent anexample structure of a database table used to store geolocation data ofthe logical topological data layer 214.

The user data layer 216 comprises data associated with a user of the ARobject system 116. The data provided by user data layer 216 can include,without limitation, data about which AR objects a given user owns orcontrols, data about the last state of a given AR object with respect toa given user, or data regarding one or more sessions associated with agiven user. The following Table 3 can represent an example structure ofa database table used to store user data of the user data layer 216

TABLE 3 Column Name Data Type Brief Description user_id Long number,Unique ID identifying a user of (serving as a the AR object systemdescribed primary key) herein. user_name Text Username for the userassociated with the user_id. timestamp Timestamp Time at which this userrecord was created or updated.

The following Table 4 can represent an example structure of a databasetable used to store data of the user data layer 216 for looking up userownership/control of an AR object.

TABLE 4 Column Name Data Type Brief Description user_id Long number IDfor user (corresponding to a (serving as a user_id in table of User Dataforeign key) Layer) associated as an owner of an AR object modelidentified by model_id model_id Long number ID for model data of ARobject (serving as a (corresponding to a model_id in foreign key) tableof Model Data Layer).

The AR object model data layer 218 comprises data for one or more ARobjects that can potentially be registered with the AR object system116.

Data stored by the AR object model data layer 218 can include, withoutlimitation, model data for generating (e.g., rendering) a 3D model thatvisually represents a given AR object, data describing a (e.g.,precalculated) 3D bounding box for a given AR object and rule datadescribe one or more rules for interacting with a given AR object. Asdescribed herein, a center of a 3D bounding box associated with a givenAR object can determine how the given AR object is positioned andoriented when displayed by a client device with respect to a real-worldenvironment (e.g., how the given AR object is embedded in real-worldspace presented by the client device). Additionally, as describedherein, one or more rules associated with a given AR object candetermine a level of user interaction available with respect to thegiven AR object. For instance, one or more rules of a given AR objectcan determine whether the AR object is static, has interactions limitedto the client device, or allows multiuser interaction over through aninteractive session.

Depending on the embodiment, the AR object model data layer 218 can beimplemented as a data structure that implements a key-value store. Thefollowing Table 5 can represent an example structure of a database tableused to store data of the AR object model data layer 218.

TABLE 5 Column Name Data Type Brief Description model_id Long number,(serving as Unique ID associated with a primary key) model data of ARobject. model_data Binary bytes Data blob used by a client device torender the 3D model of the AR object. user_id Long, foreign key into IDfor user (corresponding user_table to a user_id in table of User DataLayer) associated as an owner of this marked area.

The AR object interactive session service 232 facilitates or manages theoperation of an interactive session (hereafter, session) that enablesmultiuser interaction with respect to one or more registered AR objects(e.g., group of AR objects). As described herein, through a session,interaction data can be communicated between client devices of usersthat are jointly interacting with one or more AR objects. For someembodiments, the AR object interactive session service 232 assigns auser to a session when the user requests interaction with one or moregiven AR objects, where the assigned session is to handle the user'sinteractions with respect to the one or more given AR objects.Additionally, for some embodiments, the AR object interactive sessionservice 232 assigns a user to a session when the user requests for aplurality of users to interact together (i.e., request multiuserinteraction) with respect to one or more given AR objects. Depending onthe embodiment, the AR object interactive session service 232 can assignusers to a given session (e.g., fill the given sessions with users)using different approaches, such preferential assignment to users thatare friends, or assignment on a first-come, first-serve basis.

In response to a request from a client device of a user to participatein a session to interact (e.g., facilitate multiuser interaction) with aset of AR objects, the AR object interactive session service 232 canassign the user to an existing session (e.g., one already operating on asession server) that can service the request, or generate and assign theuser to a new session (e.g., spin up a new session on a session server)to service the request. More regarding session assignment and operationof sessions using mapping servers (e.g., world servers) and sessionservers is described herein with respect to FIGS. 3 and 4.

For some embodiments, a user is limited to participation in one sessionat a time. A user participating in a given session can idle out of thegiven session (e.g., based on lack of activity or interaction within thesession after a period of time). Further, a given session can beassigned a user participant count limit to ensure that the given sessionoperates as expected for participating users. The user participant countlimit can vary between different sessions. For instance, the userparticipant count limit can be based on the geographic area/partitionbeing serviced by the different sessions (e.g., area around a landmark,such as the Washington Monument, can likely involve more user AR objectinteractions and thus have a lower count limit than an area covering asmall city park).

For some embodiments, the client device of each user participating in agiven session shares data regarding that user's participation in thegiven session with the client devices of all other users participatingin the given session. The data can include, without limitation, theuser's inputs (e.g., swipes, head tilts, etc.) to the given session andchanges to the state of an AR object involved in the given sessioncaused by interactions of the user. For various embodiments, the sharingof data between the client device is facilitated through operations ofthe given session.

The state of an AR object involved in a session can be referred to asthe AR object's session state. The current session state of an AR objectof a session can serve as a “ground truth” for users interacting withthe AR object through the session. With respect to a given session thatis interacting with one or more given AR objects, the client device ofuser participating in (e.g., assigned to and involved in) the givensession can receive the start state of each of those given AR objects atthe start of the user's participation in the session, which the clientdevice uses to initialize the session state of each of those given ARobjects at the client device. The user can then participate in thesession by, for example, interacting with one or more of the given ARobjects, or user observing another user of the session interacting withone or more of the given AR objects. As the user participates in thegiven session, the user's client device can locally work with andmaintain (e.g., store and update) a local copy of a session state foreach of the given AR objects at the client device. For example, theclient device can update the locally maintained session state of a firstAR object of the given session based on the user interactions with thefirst AR object. Concurrently, the client device can update the locallymaintained session state of the first AR object of the given sessionbased on session state update data received by the client deviceregarding interactions with the first AR object by another userparticipating in the given session (e.g., session state update databeing broadcasted, by the other user's client device, through the givensession to all user client devices). Depending interaction level of agiven AR object (e.g., as defined by a rule associated with the given ARobject), at the termination of the given session, the final sessionstate of the given AR object can be stored (e.g., persistently stored)to the AR object system 116 (e.g., stored to the user data layer 216with respect to the users of the given session or stored for all usersvia the AR object model data layer 218). For instance, a rule of thegiven AR object can define that the given AR object can be interactedwith through a session and any changes to the session state of the givenAR object will eventually be saved to the AR object system 116. Oncethis final session state is stored to the AR object system 116, thestored session state can be used as initial/start state for the given ARobject the next time one or more users start interacting with the givenAR object again (e.g., within a new session). By maintaining localcopies of session states at client devices and saving the final state ofa given AR object (where applicable) at the end of a session, variousembodiments can enable scalability of, can also promote stability of,and reduce or can avoid/reduce overwrite thrash by the AR objectinteractive session service 232.

The AR object interactive session service 232 can support multiplesimultaneous sessions involving interaction of the same AR object. Thesessions supported by the AR object interactive session service 232 canoperate independently. Accordingly, with respect to a given AR object ofa given session, access to the state of the given AR object within thegiven session (the given AR object's session state) can be maintainedsuch that the session state cannot be accessed outside of the givensession (e.g., by a user not participating in the given session). Thismeans that two independent simultaneous sessions can involve usersinteracting with the same particular AR object, but each of thoseindependent simultaneous sessions maintains its own session state forthat particular AR object. The independence of sessions can enable someembodiments to manage (e.g., generate, assign, and operate) sessionsusing a mapping server and multiple session servers (e.g., independentsessions servers responsible for servicing sessions based ongeopartitioning of the real-world) as described herein, which canprovide scalability and stability for users. For instance, anindependent session approach means that an embodiment can provide one ormore users (within a single session) with the experience of seeing an ARobject a user of the single session created with respect to a real-worldobject (e.g., placing a virtual hate on a real-world statue) for asatisfactory amount of time (rather than less than a small amount time,which would result if all users were interacting with the given ARobject operated assigned to the same session or a session state of thegiven AR object was shared across multiple sessions). Where two or moresimultaneous sessions involve one or more same AR objects, a merge rulefunctionality can be used to merge the final sessions states of thosesame AR objects if they are to be stored after termination of thesimultaneous sessions.

More regarding operations of the AR object interactive session service232 are described herein with respect to FIGS. 3 and 4.

The AR object query service 234 processes requests or queries, fromclient devices, for one or more AR objects from the AR registryimplemented by the AR object system 116 (e.g., implemented viageolocation data of the logical topological data layer 214). Based on areceived request/query, the AR object query service 234 can determineone or more AR objects (from the AR registry) to be sent back to aclient device for use. In this way, the AR object query service 234operates as an AR object surface service, given that one or more ARobjects provided by the AR object query service 234 to a client device(e.g., based on a client request or query) causes (or likely causes) theclient device to present or surface those one or more AR objects on theclient device. The request/query to the AR object query service 234 canbe generated by a client application (e.g., 104) on a client device,where the client application can use one or more AR objects provided bythe AR object query service 234 to present with respect to a view of areal-world environment (e.g., to provide a mixed reality userexperience). As described herein, the request/query can includeinformation associated with a client device, such as such as informationregarding the user of the client device, the current set of coordinates(e.g., GPS coordinates) of the client device, or a specified radiusaround the client device.

For some embodiments, the AR object query service 234 uses one or morerankers in determining which one or more AR objects are to be sent backto a client device in response to a request/query. By a ranker, the ARobject query service 234 can prioritize, filter, or sort AR objects todetermining a final set of AR objects sent to the client device. Forexample, the AR object query service 234 can determine (e.g., identify)an intermediate/initial set of AR objects from the AR registry based onthe client request/query, and then use a ranker to filter and sort theintermediate/initial set of AR objects to determine a final set of ARobjects to be sent to the client device. Alternatively, the ranker canreceive the client request/query and generate a ranker-based query thatincludes one or more parameters for prioritizing, filtering, or sortingthe AR objects the results provided in response to the ranker-basedquery. The filter, sort, or both can be performed, for example, onattributes associated with geolocation data from the logical topologicaldata layer 214.

A ranker can be implemented such that it can be horizontally scalable.Depending on the embodiment, the AR object query service 234 can haveone or more rankers available for use. The AR object query service 234can select and use one or more rankers (from a plurality of availablerankers) based on a number of factors including, for example, based oninformation provided in the client request/query (e.g., client devicegeographical location or specific radius) or a user selection orpreference. As described herein, the AR object registry service 236 canfacilitate registration of new or existing rankers with the AR objectsystem 116, thereby enabling availability of those new/existing rankersfor use by the AR object query service 234. An example ranker caninclude a query result limit (e.g., limit to 25 AR objects). Anotherexample ranker can include an algorithm that selects AR objects based ona pseudo-random fairness and then sorts the selected AR objects.

For some embodiments, the AR object query service 234 can use a rankerthat accesses bidding data (e.g., provided by a bidding system) todetermine priorities of a set of AR objects, which can enable the ARobject query service 234 to filter the set of AR objects based on thedetermined priorities. For example, with respect to a set of AR objectsfalling within a specific radius centered at a location corresponding toa location of a client device, a ranker can access (e.g., real-time)bidding data for one or more AR objects (in the set of AR objects),which can determine the priority of those one or more AR objects.Bidding data can be accessed for each AR object by performing amonetization lookup on each AR object.

The bidding data can be provided by a bidding system, which can beseparate or part of the AR object system 116. Where separate, thebidding system can have at least read access to data of the AR objectsystem 116, such as the geolocation data of the logical topological datalayer 214, which can facilitate bidding on registration/placement of ARobjects.

Some embodiments provide for or utilize a bidding system, that permitsone or more users (e.g., representing third-party organizations) to bidon prioritizing (surfacing of) an AR object of their choosing over otherAR objects. The one or more users can bid, for example, that an ARobject of their choosing be prioritized (e.g., boosted in priority) inassociation with a set of coordinates, areas relative to (e.g., around)a set of coordinates, a marked area (e.g., described by zone data fromthe logical topological data layer 214), with respect to certain usersor types of users, and the like. For example, with respect to aregistered AR object (an AR object registered in association with a setof coordinates corresponding to a location on a map), a user can bid onboosting the priority of the registered AR object, (e.g., over other ARobjects registered/placed with respect to locations at or around thesame set of coordinates). By boosting the priority of the registered ARobject via a winning bid, a user can effectively boost thedisplay/presentation/surfacing rank of the registered AR on a clientdevice. For instance, based on a ranker associated with bidding data,the request/query result provided to a client device can include apredetermined number of top bidded AR objects. The bid can comprise avalue (e.g., monetary value or virtual credit) being offered by the bid,and can further comprise a priority value being requested by the bid(e.g., amount of priority boost or actual priority value). On thebidding system, a bid can comprise a user associating a monetaryvalue/virtual credit with a geolocation data record (e.g., postion_idcorresponding to the record) of the logical topological data layer 214.

By use of a ranker can enable the AR object system 116 to decentralizethe ability to query the AR registry for AR objects. Additionally, useof a ranker can improve user experience by improving which AR objectsare presented/surfaced to a user at a client device. For example,through use of a ranker, the AR object query service 234 can enable auser to see different types of AR objects based on, for example, thetime of year or geographic location. For instance, what AR objects auser wants to be able to see in Las Vegas is not necessarily what onewants to be able to see at a family Thanksgiving dinner.

More regarding operations of the AR object query service 234 aredescribed herein with respect to FIG. 5.

Through the AR object registry service 236, a user can manage (e.g.,add, remove, or modify) registration of an AR object in association withone or more coordinates corresponding to a location on a map (e.g.,topological map), can manage registration of a ranker in associationwith one or more coordinates corresponding to a location on a map, orboth. For example, a user can use the AR object registry service 236 togenerate a new registration of an AR object with respect to one or morecoordinates corresponding to a location on a map. The new registrationcan be for an AR object newly added to the AR object model data layer218 or already stored on the AR object model data layer 218. Asdescribed herein, registering an AR object in association with a set ofcoordinates can effectively place the AR object at a locationcorresponding to the set of coordinates (e.g., place the AR objectrelative to a real-world map to achieve mixed reality). Depending on theembodiment, a registration of AR object or a ranker can be ephemeral.

For some embodiments, the AR object registry service 236 uses permissiondata to determine whether a given user can register a given AR object, agiven ranker, or both with respect to one or more coordinates on a map.For example, as described herein, zone data from the logical topologicaldata layer 214 can provide permission data in association with one ormore areas of a real-world environment (e.g., marked areas described bythe zone data). Additionally, for some embodiments, the AR objectregistry service 236 implements one or more rate limitations withrespect to registration requests (e.g., request for adding, removing, orupdating registrations). For example, a rate limitation can define thata given user is limited to five registrations per a day through the ARobject registry service 236. In another example, a rate limitation candefine that a given user is limited to a predetermined number ofregistrations per a day, and the given user has to pay to register morethan the predetermined number within a day. With a rate limitation, someembodiments can avoid spamming the AR object registry service 236 withregistration requests.

Depending on the embodiment, the AR object registry service 236 canpermit or facilitate registration of an AR object, a ranker, or both bythe public domain (e.g., public registration). For instance, a user(e.g., from the public) can construct a new AR object or a new rankerand register this new item via the AR object registry service 236.

For some embodiments, the AR object registry service 236 stores aregistration of an AR object (with respect to a set of coordinatescorresponding to a location on a map) in the geolocation data of thelogical topological data layer 214 as described herein (e.g., usingmodel_id of TABLE 2). Similarly, for some embodiments, the AR objectregistry service 236 stores a registration of a ranker (e.g., withrespect to a set of coordinates corresponding to a location on a map) asgeolocation data of the logical topological data layer 214 as describedherein (e.g., using ranker_id of TABLE 2). Some embodiments canfacilitate registration of an AR object or a ranker in connection withan attribute of a client device (e.g., identity of a particular clientdevice, a client device type, version of operating system, etc.) or anattribute of client application (e.g., identity or version of aparticular client application or a particular client application type,such as a web browser, social networking, or messaging softwareapplication).

FIG. 3 is a block diagram illustrating an example of the AR objectinteractive session service 232, according to some embodiments. As shownin FIG. 3, the AR object interactive session service 232 comprises oneor more mapping servers 302 (e.g., world server), and one or moresession servers 304. Depending on the embodiment, a particular mappingserver 302 can determine and assign a session (operating on a particularsession server 304) to a client device, and a particular session server304 can operate one or more sessions that support user interactions(e.g., multiuser interactions) with one or more AR objects. According tosome embodiments, a client device of a user sends a request to use asession to interact (e.g., facilitate multiuser interaction) with a setof AR objects. The one or more mapping servers 302 can receive therequest, determine a particular one of the session servers 304(hereafter, the determined session server 304) to service the request,assign the user or the client device to a new or an existing sessionoperating on the determined session server 304 that can service therequest, and re-route or otherwise re-direct the client device to thedetermined session server 304. Depending on the embodiment, the mappingserver 302 can determine which of the session servers 304 is to servicea given request based on, for example, the set of coordinates of theclient device, identity of the user, current load of session servers,association of session servers 304 to marked areas (e.g.,geopartitioning) of the real-world environment. For instance, themapping server 302 can determine which of the session servers 304 is toservice a given request such that multiple simultaneous usersinteracting with the same set of AR objects are partitioned in a waythat does not overload any one of the session servers 304, whilemaintaining preferential user groupings in sessions (e.g., placing usersthat are friends together in the same session).

A given session server 304 can operate a plurality of simultaneoussessions (e.g., based on its particular load or capacity). As describedherein, a given session maintains its own session state for each of ARobject involved in the given session, and those session states aremaintained not accessible outside of the given session. A given sessionserver 304 can operate a virtual, canonical copy of a session. Oncemultiple client devices of users participating in a given session(operating on a given session server 304) have established a dataconnection with the given session, each client device can communicatedata, such as a user inputs (e.g., swipes, head tilts, etc.) or sessionstate updates to AR objects, to the given session, and the given sessioncan share the data with the other client devices connected to the givensession. A client device can share data with the given session using,for example, a low latency. User Datagram Protocol (UDP)-basedconnection. Upon receiving user inputs from a client device, the givensession can validate the user inputs (e.g., to deter or avoid bots orcheaters) and can share the validated user input to all other clientdevices (e.g., using the same low latency. UDP-based connection) so theclient devices can update their local copies of session states of ARobjects based on the validated user inputs accordingly. The givensession can also update some session information based on the validateduser inputs.

FIG. 4 is a flow diagram illustrating an example of session handling byan AR object interactive session service (e.g., 232), according to someembodiments. At the start, a client application operating on a clientdevice 404 can cause the client device 404 to request/query for one ormore AR objects from an AR object query service 402 (e.g., request/querybased on a set of coordinates corresponding to the current location ofthe client device 404 and a radius value). At operation 420, the clientdevice 404 can download data for the one or more AR objects that resultfrom the request/query, which can include model data and rule data forthe one or more AR objects. Subsequently, the user can interact with theone or more AR objects in accordance with one or more rules described bythe rule data. Eventually, the user may request a session to facilitatemultiuser interaction with respect to at least one of the one or more ARobjects. Accordingly, at operation 422, the client device 404 caninitialize a connection with a mapping server 406 (e.g., world server),which can enable the client device 404 to send its request for asession. In response to the request, at operation 424, the mappingserver 406 can check an AR object interactive session cache 410 todetermine whether there are any existing sessions associated with the atleast one AR object (to which the client device 404 can be assigned), orwhether a new session needs to be created for the request. In FIG. 4,the AR object interactive session cache 410 can cache informationregarding sessions currently being operated by one or more sessionservers. Accordingly, a session server such as session server 408 canperiodically update information stored on AR object interactive sessioncache 410 (as represented by operation 428). After the mapping server406 identifies and assigns the client device 404 to a new or existingsession, at operation 426, the mapping server 406 can redirect theclient device 404 to the session server operating the assigned session(representing by the session server 408). Once redirected to the sessionserver 408 and a data connection with the assigned session isestablished, at operation 430, the client device can send its user'sinputs to the assigned session (to be shared by the assigned sessionwith other client devices connected to the assigned session), and theclient device can receive user inputs from client devices of other usersparticipating in the assigned session. Based on the received userinputs, the client device 404 can update its local copy of sessionstates for AR objects involved in the assigned session.

FIG. 5 is a flow diagram illustrating an example of using one or morerankers for providing a client device with one or more AR objects,according to some embodiments. At the start, a client applicationoperating on a client device 502 can cause the client device 502 torequest/query for one or more AR objects from an AR object query service504 (e.g., request/query based on a set of coordinates corresponding tothe current location of the client device 404 and a radius value).Operation 530 can represent the client device 502 sending therequest/query to the AR object query service 504. The request/query canresult from a user of the client device 502 using the client device 502(e.g., smartphone) to scan their surrounding real-world environment forAR objects.

The AR object query service 504 can determine one or more rankersassociated with the received request/query (e.g., based on a set ofcoordinates provided by the request/query). One of the determinedrankers can be one that accesses bidding data from a bidding system 506at operation 532 and prioritizes one or more AR objects over other ARobjects. As described herein, the bidding system 506 can enable a userto bid on prioritizing (e.g., boosting the priority of) a registered ARobject. At operation 534, the AR object query service 504 can querygeolocation data 508 to determine an intermediate set of AR objectsassociated with coordinates within a radius of the client device 502'scurrent geographic location, and then apply the one or more determinedrankers to the intermediate set of AR objects (e.g., filter or sort theintermediate set of AR objects) to reach a final set of AR objects. Atoperation 536, the AR object query service 504 can obtain (e.g., fetch)data for the final set of AR objects, which can include, for example,data from AR object model data 510 and rule data associated with thefinal set of AR objects. At operation 538, the data for the final set ofAR objects is provided to and downloaded by the client device 502 (asrepresented by 512). At operation 540, the client device 502 candetermine positioning of a virtual camera with respect to a display ofthe client device 502 (as represented by 514) and, at operation 542, theclient device 502 can display rendered models of one or more of the ARobjects from the final set based on the positioned virtual camera (asrepresented by 516). Subsequently, the user of the client device 502 caninteract with the AR objects displayed on the client device 502.

FIG. 6 is a block diagram illustrating an example implementation of theAR object system 116, according to some embodiments. The AR objectsystem 116 is shown as including an augmented reality (AR) object querymodule 602, an augmented reality (AR) object interactive session module604, an augmented reality (AR) object registry module 606, an augmentedreality (AR) object bidding module 608, a three-dimensional (3D)topological data module 610, a logical topological data module 612, auser data module 614, and an augmented reality (AR) object model datamodule 616. The various modules of the AR object system 116 areconfigured to communicate with each other (e.g., via a bus, sharedmemory, or a switch). Any one or more of these modules may beimplemented using one or more processors 600 (e.g., by configuring suchone or more processors 600 to perform functions described for thatmodule) and hence may include one or more of the processors 600.

Any one or more of the modules described may be implemented usinghardware alone (e.g., one or more of the computer processors of amachine, such as machine 1500) or a combination of hardware andsoftware. For example, any described module of the AR object system 116may physically include an arrangement of one or more of the processors600 (e.g., a subset of or among the one or more processors of themachine, such the machine 1500) configured to perform the operationsdescribed herein for that module. As another example, any module of theAR object system 116 may include software, hardware, or both, thatconfigure an arrangement of one or more processors 600 (e.g., among theone or more processors of the machine, such as the machine 1500)) toperform the operations described herein for that module. Accordingly,different modules of the AR object system 116 may include and configuredifferent arrangements of such processors 600 or a single arrangement ofsuch processors 600 at different points in time. Moreover, any two ormore modules of the AR object system 116 may be combined into a singlemodule, and the functions described herein for a single module may besubdivided among multiple modules.

For some embodiments, a set of world servers and a set of sessionservers used to implement or operate the AR object interactive sessionmodule 604. Additionally, for some embodiments, the AR object querymodule 602 is implemented or operates on a set of query servers that areseparate from the set of world servers and the set of session serversused to operate the AR object interactive session module 604. Moreregarding modules 602-616 is described below with respect to operationsof the methods depicted by FIGS. 7-13.

FIGS. 7 through 13 are flowcharts illustrating methods relating to an ARobject registry, according to some embodiments. Various methodsdescribed herein with respect to FIGS. 7 through 13 may be embodied inmachine-readable instructions for execution by one or more computerprocessors such that the operations of the methods may be performed inpart or in whole by the server system 108 or, more specifically, the ARobject system 116. Accordingly, various methods are described herein byway of example with reference to the AR object system 116. At least someof the operations of the method 800 may be deployed on various otherhardware configurations, and the methods described herein are notintended to be limited to being operated by the server system 108.Though the steps of the methods described herein may be depicted anddescribed in a certain order, the order in which the operations areperformed may vary between embodiments. For example, an operation may beperformed before, after, or concurrently with another operation.Additionally, the components described with respect to the methods aremerely examples of components that may be used with the methods, andother components may also be utilized, in some embodiments.

Referring now to FIG. 7, a method 700 is illustrated for providing ARobjects to a client device and handling a session for interacting with aprovided AR object. At operation 702, the AR object query module 602receives a query from a client device for one or more augmented realityobjects, where the query can comprise a current set of coordinates thatcorresponds to a position of the client device on a map, and can furthercomprise a radius relative to (e.g., centered by a locationcorresponding to) the current set of coordinates.

In response to the query received at operation 702, at operation 704,the AR object query module 602 determines (e.g., identifies) a set ofaugmented reality objects based on the query and, at operation 706,sends a query result to the client device, where the query resultcomprises result data for the set of augmented reality objectsdetermined by operation 704. The determination of the set of augmentedreality objects based on the query can comprise the AR object querymodule 602 executing a search based on the received query. The set ofaugmented reality objects can be determined by operation 704 from aplurality of augmented reality objects registered on an augmentedreality object registry (e.g., as registered via the AR object registrymodule 606). As described herein, based on the result data provided tothe client device by the query result, the client device can display (orsurface) one or more of the augmented reality objects from the set ofaugmented reality objects.

Depending on the embodiment, the result data can comprise a currentstored state of the at least one augmented reality object (state storedon the AR object system 116), where the current stored state onceprovided to the client device can determine an initial state of the atleast one augmented reality object for the user on the client device.The result data can comprise model data for each augmented realityobject in the set of augmented reality objects. The result data cancomprise location (e.g., position) data that describes, for eachaugmented reality object in the set of augmented reality objects, agiven set of coordinates on the map at which the augmented realityobject is to be displayed by a given client device when the given clientdevice generates an augmented reality view relative to the given set ofcoordinates. The result data can comprise orientation data thatdescribes, for each augmented reality object in the set of augmentedreality objects, a given orientation at which a given client device isto display the augmented reality object when the client device generatesan augmented reality view that includes the augmented reality object.Additionally, the result data can comprise rule data that describes aset of interaction rules associated with the set of augmented realityobjects, where the set of interaction rules can determine interactionsavailable to the user (on the first client device) with respect to theset of augmented reality objects. The augmented reality registry of theAR object system 116 can associate a given augmented reality object withone or more interaction rules.

At operation 708, the AR object interactive session module 604 receives,from the client device, a request for a user at the client device tointeract with at least one augmented reality object in the set ofaugmented reality objects (determined at operation 704 and for which thequery result was sent to the client device at operation 706).

In response to the request received at operation 708, at operation 710,the AR object interactive session module 604 determines (e.g.,identifies) a given session server to service the request received atoperation 708 and, at operation 712, assigns the client device to agiven session operating on the given session server. The given sessioncan be a new session created by the given session in response to therequest, or an existing session that involves the same set of AR objectsassociated with the request. For some embodiments, the AR objectinteractive session module 604 can check a session cache to determinewhether a relevant, existing session already exists for the request. Thegiven session server determined at operation 710 can be associated witha geographic partition of the map that contains the position of theclient device on the map. As described herein, the given session canfacilitate interaction with the at least one augmented reality object bythe user of the client device. Additionally, as described herein, thegiven session can maintain a session state for the at least oneaugmented reality object with respect to one or more users associatedwith (e.g., participating in) the given session, where the session statecan be updated based on interaction of at least one of the users withthe at least one augmented reality object. The given session server canbe determined from a plurality of given session servers (e.g., 304), amapping server (e.g., 302) can perform the determination of the givensession server. For some embodiments, the plurality of session serversoperates on a first set of computer devices that is separate from asecond set of computer devices operating the mapping server. For someembodiments, assigning the first client device to the given sessionoperating on the given session server comprises redirecting the clientdevice from the mapping server to the given session server. Once thegiven session is assigned to the user, the user data can be updated viathe user data module 614. Subsequent to the assignment, a networkconnection can be established between the client device and the(assigned) given session on the given session server.

Referring now to FIG. 8, a method 800 is illustrated for providing ARobjects to a client device and handling a session for a plurality ofusers to interact with a provided AR object. For some embodiments,operations 802 through 806 are respectively similar to operation 702through 706 of the method 700 described above with respect to FIG. 7,and performed with respect to a first client device (associated with afirst user). At operation 808, the AR object interactive session module604 receives, from the first client device, a request for a plurality ofusers to interact together (e.g., multiuser interactive session) with atleast one augmented reality object in the set of augmented realityobjects (determined at operation 804 and for which the query result wassent to the first client device at operation 806). As described herein,a multiuser interactive session can facilitate interaction by aplurality of users with the at least one augmented reality object.

In response to the request received at operation 808, at operation 810,the AR object interactive session module 604 determines (e.g.,identifies) a given session server to service the request received atoperation 808 and, at operation 812, assigns the first client device toa given session operating on the given session server. As describedherein, the given session server determined at operation 810 can beassociated with a geographic partition of the map that contains theposition of the first client device on the map. Additionally, atoperation 814, the AR object interactive session module 604 assigns asecond client device associated with a second user to the same givensession operating on the same given session server (determined atoperation 810), where the first user of the first client device and thesecond user of the second client device are part of the plurality ofusers for which session request was received at operation 808.Additionally, other users of the plurality of users can be assigned tothe same given session on the same given session server in a similarmanner.

Referring now to FIG. 9, a method 900 is illustrated for providing ARobjects to a client device and handling a session for interacting with aprovided AR object. For some embodiments, operations 902 through 912 aresimilar to operation 702 through 712 of the method 700 described abovewith respect to FIG. 7. At operation 914, at termination of the givensession, the AR object interactive session module 604 stores (or causesthe storage) of a final version of a session state of the at least oneaugmented reality object. As described herein, the final version of asession state of a given augmented reality object can be determined(e.g., adjusted) by interactions of users participating in the givensession.

Referring now to FIG. 10, a method 1000 is illustrated for registeringan AR object to an AR object registry. At operation 1002, the AR objectregistry module 606 receives, from a client device associated with auser, a request to register a given augmented reality object on anaugmented reality object registry in association with a given set ofcoordinates on the map.

In response to the request received at operation 1002, at operation1004, the AR object registry module 606 determines, based on permissiondata, whether the user has permission to register the given augmentedreality object in association with the given set of coordinates on themap. For some embodiments, the permission data describes an associationbetween at least one set of coordinates on the map and a set ofpermissions. The permission data can be associated with a marked area ofthe map that contains the given set of coordinates. Accordingly, forsome embodiments, the permission data can be provided by zone dataaccessible through the logical topological data module 612.

Additionally, in response to the request received at operation 1002,operation 1006 is performed. At operation 1006, based on the determiningwhether the user has permission, the AR object registry module 606registers the given augmented reality object on the augmented realityobject registry in association with the given set of coordinates on themap. When doing so, the AR object registry module 606 can designate theuser as the owner or controller of the registration.

Referring now to FIG. 11, a method 1100 is illustrated for providing ARobjects to a client device based on one or more rankers. At operation1102, the AR object query module 602 receives a query from a clientdevice for one or more augmented reality objects, where the query cancomprise a current set of coordinates that corresponds to a position ofthe client device on a map, and can further comprise a radius relativeto (e.g., centered by a location corresponding to) the current set ofcoordinates.

In response to the query received at operation 1102, at operation 1104,the AR object query module 602: determines (e.g., identifies) anintermediate set of augmented reality objects based on the query; atoperation 1106, determining a set of rankers for the query, where atleast one ranker in the set of rankers is configured to filter or sort aset of augmented reality objects; and at operation 1108, generates afinal set of augmented reality objects by applying the set of rankers(e.g., filtering or sorting according to the rankers) to theintermediate set of augmented reality objects. An example ranker caninclude one that applies at least one of a filter or a sort order to aset of augmented reality objects.

Another example ranker can include one that filters a set of augmentedreality objects based on a set of priorities for the set of augmentedreality objects. The priorities can be provided (or determined), forexample, by geolocation data (e.g., provided via the logical topologicaldata module 612) or by bidding data (e.g., provided via the AR objectbidding module 608) that is associated with one or more of the augmentedreality objects. As described herein, a bidding system (e.g.,implemented by the AR object bidding module 608) can enable a user toplace a bid on an AR object registration to adjust (e.g., boost) thepriority of that AR object registration. Through the AR object biddingmodule 608, a ranker can: request, from a bidding system, priorityinformation for a set of augmented reality objects, and receive, fromthe bidding system, priority data that describes priorities for at leastone of the set of augmented reality objects.

The determination (e.g., identification) of at least one of the rankerscan be based on an association of the ranker to the user of the clientdevice (e.g., user selected use of the ranker or registered by theuser). The determination of at least one of the rankers can be based onthe current set of coordinates corresponding to the location of theclient device. In doing so, a ranker can be applied to a radius aroundthe client device. The determination of at least one of the rankers canbe based on an attribute of a client device, such as the identity of theclient device or a device type of the client device. The determinationof at least one of the rankers can be based on at least one of a set(e.g., range) of dates or a set of times. In doing so, a ranker can beapplied based on different portions of the years (e.g., according toseasons of the year).

As alternative to operations 1104 through 1108, for some embodiments, inresponse to the query received at operation 1102, the AR object querymodule 602: determines a set of rankers for the client query (e.g.,where at least one ranker in the set of rankers comprises a filterparameter for filtering a set of augmented reality objects or a sortorder parameter for sorting a set of augmented reality objects); andgenerates (e.g., constructs) a query (a ranker-based query) based on theclient query and the set of rankers; and then determines (e.g.,identifies) a final set of augmented reality objects based on theranker-based query.

At operation 1110, the AR object query module 602 sends a query resultto the client device, where the query result comprises result data forthe final set of augmented reality objects (e.g., the final set asdetermined by operation 1108 or the alternative approach). As describedherein, the result data for the final set of augmented reality objectscan comprise various types of data (e.g., location data, model data,orientation data, etc.) for one or more of the augmented reality objectsin the final set.

Referring now to FIG. 12, a method 1200 is illustrated for providing ARobjects to a client device based on one or more rankers involving abidding system. For some embodiments, operations 1202 through 1206 arerespectively similar to operation 1102 through 1106 of the method 1100described above with respect to FIG. 11. At operation 1208, the ARobject query module 602 requests, from a bidding system (via the ARobject bidding module 608), priority information for the intermediateset of augmented reality objects determined at operation 1204. For someembodiments, operation 1208 is performed based on at least one of therankers determined at operation 1206 (e.g., the ranker uses priorityinformation of augmented reality objects to filter or sort them). Atoperation 1210, the AR object query module 602 receives, from thebidding system, priority data (or bidding data) that describes apriority for at least one augmented reality object in the intermediateset of augmented reality objects.

For some embodiments, operations 1212 and 1214 are respectively similarto operation 1108 and 1110 of the method 1100 described above withrespect to FIG. 11. As described herein, the priority informationobtained via operations 1208 and 1210 can enable a ranker applied to theintermediate set of augmented reality objects (by operation 1212) tofilter or sort the intermediate set of augmented reality objects.

Referring now to FIG. 13, a method 1300 is illustrated for registering aranker to a ranker registry (which may be implemented as part of the ARobject registry). At operation 1302, the AR object registry module 606receives, from a client device associated with a user, a request toregister a given ranker on a ranker registry (e.g., in association withthe given set of coordinates on the map, the marked area, with aspecific client device, a client device type, user, type of user, timeof day, date, season, etc.).

In response to the request received at operation 1302, at operation1304, the AR object registry module 606 determines, based on permissiondata, whether the user has permission to register the given ranker. Forsome embodiments, the permission data describes an association betweenat least one set of coordinates on the map and a set of permissions. Thepermission data can be associated with a marked area of the map thatcontains the given set of coordinates. Accordingly, for someembodiments, the permission data can be provided by zone data accessiblethrough the logical topological data module 612.

Additionally, in response to the request received at operation 1302,operation 1306 is performed. At operation 1306, based on the determiningwhether the user has permission, the AR object registry module 606registers the given ranker on the ranker registry (e.g., in associationwith the given set of coordinates on the map, the marked area, with aspecific client device, a client device type, user, type of user, timeof day, date, season, etc.). When doing so, the AR object registrymodule 606 can designate the user as the owner or controller of theregistration. The ranker can be registered for use by the user only, oropen for use by other users on the AR object system 116.

FIG. 14 is a block diagram illustrating an example software architecture1406, which may be used in conjunction with various hardwarearchitectures herein described. FIG. 14 is a non-limiting example of asoftware architecture and it will be appreciated that many otherarchitectures may be implemented to facilitate the functionalitydescribed herein. The software architecture 1406 may execute on hardwaresuch as machine 1500 of FIG. 15 that includes, among other things,processors 1504, memory/storage 1506, and I/O components 1518. Arepresentative hardware layer 1452 is illustrated and can represent, forexample, the machine 1500 of FIG. 15. The representative hardware layer1452 includes a processing unit 1454 having associated executableinstructions 1404. Executable instructions 1404 represent the executableinstructions of the software architecture 1406, including implementationof the methods, components and so forth described herein. The hardwarelayer 1452 also includes memory or storage modules memory/storage 1456,which also have executable instructions 1404. The hardware layer 1452may also comprise other hardware 1458.

In the example architecture of FIG. 14, the software architecture 1406may be conceptualized as a stack of layers where each layer providesparticular functionality. For example, the software architecture 1406may include layers such as an operating system 1402, libraries 1420,applications 1416, and a presentation layer 1414. Operationally, theapplications 1416 or other components within the layers may invokeapplication programming interface (API) calls 1408 through the softwarestack and receive a response in the example form of messages 1412 to theAPI calls 1408. The layers illustrated are representative in nature andnot all software architectures have all layers. For example, some mobileor special purpose operating systems may not provide aframeworks/middleware 1418, while others may provide such a layer. Othersoftware architectures may include additional or different layers.

The operating system 1402 may manage hardware resources and providecommon services. The operating system 1402 may include, for example, akernel 1422, services 1424 and drivers 1426. The kernel 1422 may act asan abstraction layer between the hardware and the other software layers.For example, the kernel 1422 may be responsible for memory management,processor management (e.g., scheduling), component management,networking, security settings, and so on. The services 1424 may provideother common services for the other software layers. The drivers 1426are responsible for controlling or interfacing with the underlyinghardware. For instance, the drivers 1426 include display drivers, cameradrivers. Bluetooth® drivers, flash memory drivers, serial communicationdrivers (e.g., Universal Serial Bus (USB) drivers), Wi-Fi® drivers,audio drivers, power management drivers, and so forth depending on thehardware configuration.

The libraries 1420 provide a common infrastructure that is used by theapplications 1416 or other components or layers. The libraries 1420provide functionality that allows other software components to performtasks in an easier fashion than to interface directly with theunderlying operating system 1402 functionality (e.g., kernel 1422,services 1424, or drivers 1426). The libraries 1420 may include systemlibraries 1444 (e.g., C standard library) that may provide functionssuch as memory allocation functions, string manipulation functions,mathematical functions, and the like. In addition, the libraries 1420may include API libraries 1446 such as media libraries (e.g., librariesto support presentation and manipulation of various media formats suchas MPEG4, H.264. MP3. AAC, AMR, JPG, PNG), graphics libraries (e.g., anOpenGL framework that may be used to render 2D and 3D graphic content ona display), database libraries (e.g., SQLite that may provide variousrelational database functions), web libraries (e.g., WebKit that mayprovide web browsing functionality), and the like. The libraries 1420may also include a wide variety of other libraries 1448 to provide manyother APIs to the applications 1416 and other softwarecomponents/modules.

The frameworks/middleware 1418 (also sometimes referred to asmiddleware) provide a higher-level common infrastructure that may beused by the applications 1416 or other software components/modules. Forexample, the frameworks/middleware 1418 may provide various graphic userinterface (GUI) functions, high-level resource management, high-levellocation services, and so forth. The frameworks/middleware 1418 mayprovide a broad spectrum of other APIs that may be used by theapplications 1416 or other software components/modules, some of whichmay be specific to a particular operating system 1402 or platform.

The applications 1416 include built-in applications 1438 or third-partyapplications 1440. Examples of representative built-in applications 1438may include, but are not limited to, a contacts application, a browserapplication, a book reader application, a location application, a mediaapplication, a messaging application, or a game application. Third-partyapplications 1440 may include an application developed using theANDROID™ or IOS™ software development kit (SDK) by an entity other thanthe vendor of the particular platform, and may be mobile softwarerunning on a mobile operating system such as IOS™, ANDROID™, WINDOWS®Phone, or other mobile operating systems. The third-party applications1440 may invoke the API calls 1408 provided by the mobile operatingsystem (such as operating system 1402) to facilitate functionalitydescribed herein.

The applications 1416 may use built-in operating system functions (e.g.,kernel 1422, services 1424, or drivers 1426), libraries 1420, andframeworks/middleware 1418 to create user interfaces to interact withusers of the system. Alternatively, or additionally, in some systems,interactions with a user may occur through a presentation layer, such aspresentation layer 1414. In these systems, the application/component“logic” can be separated from the aspects of the application/componentthat interact with a user.

Accordingly, the memory 1514, thestorage unit 1516, and the memory of processors 1504 are examples ofmachine-readable media.

The I/O components 1518 may include a wide variety of components toreceive input, provide output, produce output, transmit information,exchange information, capture measurements, and so on. The specific I/Ocomponents 1518 that are included in a particular machine 1500 willdepend on the type of machine. For example, portable machines such asmobile phones will likely include a touch input device or other suchinput mechanisms, while a headless server machine will likely notinclude such a touch input device. It will be appreciated that the I/Ocomponents 1518 may include many other components that are not shown inFIG. 15. The I/O components 1518 are grouped according to functionalitymerely for simplifying the following discussion and the grouping is inno way limiting.

Glossary

“AUGMENTED REALITY OBJECT” in this context can refer to a virtual object(e.g., two dimension or three dimensional virtual objects) that can bepresented in a client device-generated view of a real-world environment(e.g., a view presented on a display of a mobile client device), wherethe virtual object can interact with or enhance a real-world physicalobject of the real-world environment presented in the view. For example,using a camera of a smartphone, a user can view their surroundingreal-world environment through the smartphone's display and thesmartphone can enhance that view by displaying (e.g., superimposing) oneor more virtual objects (e.g., three dimensional virtual objects) in theview in connection with one or more particular real-world physicalobjects of the real-world environment. For instance, an augmentedreality object can be combined with a live (e.g., real-time or nearreal-time) camera feed such that when the augmented reality object ispresented, it appears situated in the live a three-dimensionalenvironment (e.g., augmented reality object appears to occupy aconsistent three-dimensional volume and dynamically changing in aspectresponsive to movement of the camera in a manner similar to that whichwould have been the case were the AR object a real-world physicalobject). In addition to visual information, a client device can conveyto a user other sensory information in association with a particularaugmented reality object, such as auditory information (e.g., music) andhaptic information.

“MIXED REALITY” in this context can refer to a merger of real-worldenvironment and a virtual world environment (that can include one ormore augmented reality objects) to generate new visualizations through aclient device. The new visualizations can enhance one or more real-worldphysical objects of the real-world environment.

Additionally, within mixed realty, a user can usethe client device to interact in real time with the augmented realityobjects.

“CLIENT DEVICE” in this context can refer to any machine that interfacesto a communications network to obtain resources from one or more serversystems or other client devices. A client device may be, but is notlimited to, a mobile phone, desktop computer, laptop, portable digitalassistants (PDAs), smart phones, tablets, ultra books, netbooks,laptops, multi-processor systems, microprocessor-based or programmableconsumer electronics, game consoles, set-top boxes, or any othercommunication device that a user may use to access a network.

“COMMUNICATIONS NETWORK” in this context can refer to one or moreportions of a network that may be an ad hoc network, an intranet, anextranet, a virtual private network (VPN), a local area network (LAN), awireless LAN (WLAN), a wide area network (WAN), a wireless WAN (WWAN), ametropolitan area network (MAN), the Internet, a portion of theInternet, a portion of the Public Switched Telephone Network (PSTN), aplain old telephone service (POTS) network, a cellular telephonenetwork, a wireless network, a Wi-Fi® network, another type of network,or a combination of two or more such networks. For example, a network ora portion of a network may include a wireless or cellular network andthe coupling may be a Code Division Multiple Access (CDMA) connection, aGlobal System for Mobile communications (GSM) connection, or other typeof cellular or wireless coupling. In this example, the coupling mayimplement any of a variety of types of data transfer technology, such asSingle Carrier Radio Transmission Technology (1×RTT), Evolution-DataOptimized (EVDO) technology. General Packet Radio Service (GPRS)technology, Enhanced Data rates for GSM Evolution (EDGE) technology,third Generation Partnership Project (3GPP) including 3G, fourthgeneration wireless (4G) networks, Universal Mobile TelecommunicationsSystem (UMTS), High Speed Packet Access (HSPA).

“EMPHEMERAL” in this context can describe an item that is accessible fora time-limited duration. An ephemeral item may be an AR object, text, animage, a video and the like. The access time for the ephemeral item maybe set by the item owner or originator (e.g., message sender or userregistering the AR object). Alternatively, the access time may be adefault setting or a setting specified by accessing user (e.g., therecipient or the user attempting to access the registered AR object).Regardless of the setting technique, the ephemeral item is transitory.

“MACHINE-READABLE MEDIUM” in this context can refer to a component,device or other tangible media able to store instructions and datatemporarily or permanently and may include, but is not be limited to,random-access memory (RAM), read-only memory (ROM), buffer memory, flashmemory, optical media, magnetic media, cache memory, other types ofstorage (e.g., Erasable Programmable Read-Only Memory (EEPROM)) and/orany suitable combination thereof. The term “machine-readable medium”should be taken to include a single medium or multiple media (e.g., acentralized or distributed database, or associated caches and servers)able to store instructions. The term “machine-readable medium” shallalso be taken to include any medium, or combination of multiple media,that is capable of storing instructions (e.g., code) for execution by amachine, such that the instructions, when executed by one or moreprocessors of the machine, cause the machine to perform any one or moreof the methodologies described herein. Accordingly, a “machine-readablemedium” refers to a single storage apparatus or device, as well as“cloud-based” storage systems or storage networks that include multiplestorage apparatus or devices. The term “machine-readable medium”excludes signals per se.

“COMPONENT” in this context can refer to a device, physical entity orlogic having boundaries defined by function or subroutine calls, branchpoints, application program interfaces (APIs), or other technologiesthat provide for the partitioning or modularization of particularprocessing or control functions. Components may be combined via theirinterfaces with other components to carry out a machine process. Acomponent may be a packaged functional hardware unit designed for usewith other components and a part of a program that usually performs aparticular function of related functions. Components may constituteeither software components (e.g., code embodied on a machine-readablemedium) or hardware components. A “hardware component” is a tangibleunit capable of performing certain operations and may be configured orarranged in a certain physical manner. In various embodiments, one ormore computer systems (e.g., a standalone computer system, a clientcomputer system, or a server computer system) or one or more hardwarecomponents of a computer system (e.g., a processor or a group ofprocessors) may be configured by software (e.g., an application orapplication portion) as a hardware component that operates to performcertain operations as described herein. A hardware component may also beimplemented mechanically, electronically, or any suitable combinationthereof. For example, a hardware component may include dedicatedcircuitry or logic that is permanently configured to perform certainoperations. A hardware component may be a special-purpose processor,such as a Field-Programmable Gate Array (FPGA) or an ApplicationSpecific Integrated Circuit (ASIC). A hardware component may alsoinclude programmable logic or circuitry that is temporarily configuredby software to perform certain operations. For example, a hardwarecomponent may include software executed by a general-purpose processoror other programmable processor. Once configured by such software,hardware components become specific machines (or specific components ofa machine) uniquely tailored to perform the configured functions and areno longer general-purpose processors. It will be appreciated that thedecision to implement a hardware component mechanically, in dedicatedand permanently configured circuitry, or in temporarily configuredcircuitry (e.g., configured by software) may be driven by cost and timeconsiderations. Accordingly, the phrase “hardware component” (or“hardware-implemented component”) should be understood to encompass atangible entity, be that an entity that is physically constructed,permanently configured (e.g., hardwired), or temporarily configured(e.g., programmed) to operate in a certain manner or to perform certainoperations described herein. Considering embodiments in which hardwarecomponents are temporarily configured (e.g., programmed), each of thehardware components need not be configured or instantiated at any oneinstance in time. For example, where a hardware component comprises ageneral-purpose processor configured by software to become aspecial-purpose processor, the general-purpose processor may beconfigured as respectively different special-purpose processors (e.g.,comprising different hardware components) at different times. Softwareaccordingly configures a particular processor or processors, forexample, to constitute a particular hardware component at one instanceof time and to constitute a different hardware component at a differentinstance of time. Hardware components can provide information to, andreceive information from, other hardware components. Accordingly, thedescribed hardware components may be regarded as being communicativelycoupled. Where multiple hardware components exist contemporaneously,communications may be achieved through signal transmission (e.g., overappropriate circuits and buses) between or among two or more of thehardware components. In embodiments in which multiple hardwarecomponents are configured or instantiated at different times,communications between such hardware components may be achieved, forexample, through the storage and retrieval of information in memorystructures to which the multiple hardware components have access. Forexample, one hardware component may perform an operation and store theoutput of that operation in a memory device to which it iscommunicatively coupled. A further hardware component may then, at alater time, access the memory device to retrieve and process the storedoutput. Hardware components may also initiate communications with inputor output devices, and can operate on a resource (e.g., a collection ofinformation). The various operations of example methods described hereinmay be performed, at least partially, by one or more processors that aretemporarily configured (e.g., by software) or permanently configured toperform the relevant operations. Whether temporarily or permanentlyconfigured, such processors may constitute processor-implementedcomponents that operate to perform one or more operations or functionsdescribed herein. As used herein. “processor-implemented component”refers to a hardware component implemented using one or more processors.Similarly, the methods described herein may be at least partiallyprocessor-implemented, with a particular processor or processors beingan example of hardware. For example, at least some of the operations ofa method may be performed by one or more processors orprocessor-implemented components. Moreover, the one or more processorsmay also operate to support performance of the relevant operations in a“cloud computing” environment or as a “software as a service” (SaaS).For example, at least some of the operations may be performed by a groupof computers (as examples of machines including processors), with theseoperations being accessible via a network (e.g., the Internet) and viaone or more appropriate interfaces (e.g., an Application ProgramInterface (API)). The performance of certain of the operations may bedistributed among the processors, not only residing within a singlemachine, but deployed across a number of machines. In some embodiments,the processors or processor-implemented components may be located in asingle geographic location (e.g., within a home environment, an officeenvironment, or a server farm). In other embodiments, the processors orprocessor-implemented components may be distributed across a number ofgeographic locations.

“PROCESSOR” in this context can refer to any circuit or virtual circuit(a physical circuit emulated by logic executing on an actual processor)that manipulates data values according to control signals (e.g.,“commands”, “op codes”, “machine code”, etc.) and which producescorresponding output signals that are applied to operate a machine. Aprocessor may, for example, be a Central Processing Unit (CPU), aReduced Instruction Set Computing (RISC) processor, a ComplexInstruction Set Computing (CISC) processor, a Graphics Processing Unit(GPU), a Digital Signal Processor (DSP), an Application SpecificIntegrated Circuit (ASIC), a Radio-Frequency Integrated Circuit (RFIC)or any combination thereof. A processor may further be a multi-coreprocessor having two or more independent processors (sometimes referredto as “cores”) that may execute instructions contemporaneously.

“TIMESTAMP” in this context can refer to a sequence of characters orencoded information identifying when a certain event occurred, forexample giving date and time of day, sometimes accurate to a smallfraction of a second.
